SLS-PT for AR in EPIC-KITCHENS:

SLS-1-X-X: standard pre-training, in this case would be any image-based pre-training.

SLS-2-X-X: Relevant pre-training would be video pretraining (e.g. large scale video datasets such as Kinetics [1]} or HowTo100M [2]}).


SLS-TL for AR in EPIC-KITCHENS:

SLS-X-1-X: Would be utilising no temporal information about action segments or instances per video, i.e. video-level labels of actions are only known, without their rough or exact locations.

SLS-X-2-X: Would utilise weak temporal labels, known as single timestamps in EPIC-KITCHENS [3]}. These are rough single time points within or close to the action of interest.

SLS-X-3-X: Full temporal labels (i.e. start-end times) without any spatial labels have been used.

SLS-X-4-X: Methods have taken advantage of spatio-temporal labels, i.e. start-end times plus bounding boxes, hand detections and/or masks.


SLS-TD for AR in EPIC-KITCHENS: No adjustments needed to adapt this dimension. Train and Val splits correspond to the splits in Table 1 from [4]}.
